Please explain the right solution of the given question
Question- A new grocery store is opening. It is 100 m long by 150 m wide and can fit 20,000 items. The temperature is really hot and the all the items need to be cooled. While cooling, each item produces 0.01g/min of carbon monoxide. Thankfully, clean fresh air is being brought in along one side of the store by wind blowing at 15 m/s. Assume a mixing depth of 12.5 meters has formed due to atmospheric conditions.
Part 1- What would be the steady state concentration of carbon monoxide in the grocery store ((use a value of 43.2 mg of CO/m3 as the standard)?
I want experts help to define the steady state concentration of carbon monoxide in grocery store.
